The air in the hole 1a can be sucked out. By such a decompression process for decompressing the inside of the accommodation hole 1a, the work W can be more firmly fixed by the work clamp 1.

  Further, according to the work clamp 1, the opened vacuum hole can be switched by moving the base movable plate 11. Therefore, it is possible to perform the switching in accordance with the fixed position of the workpiece W and appropriately execute the decompression process regardless of the fixed position of the workpiece W.

  For example, when the workpiece W is positioned to the left as shown in FIG. 11B, the left vacuum holes (12p, 12q) can be opened by moving the base movable plate 11 to the left. Thereby, it is possible to depressurize the left region in the accommodation hole 1a corresponding to the position of the workpiece W and firmly fix the workpiece W.

Can be made flexible.

  In addition, the x-direction movable plate 14 and the y-direction movable plate 13 have elastic members (springs) provided on the inner peripheral surface of the accommodation hole 1a, and in a state where the housed workpiece W is moved to a fixed position. The elastic member is formed so as to bias the workpiece W. Therefore, according to the clamp tray 1, it is easy to grip and fix the workpiece W with an appropriate force.

  In the clamp tray 1, the cover plate 15, the x-direction movable plate 14, and the y-direction movable plate 13 are formed with accommodation holes 1a. In the base plate 12, the region exposed in the accommodation hole 1a (the depression 1a ') is formed. A plurality of vacuum holes (two first vacuum holes 12p and two second vacuum holes 12q) are provided.

  Thereby, the clamp tray 1 can suck out the air in the accommodation hole 1a through the one opened to the outside (the back side of the base movable plate 11) among the plurality of vacuum holes. Further, in the clamp tray 1, a base movable plate 11 that is movable so as to switch the opened vacuum hole is laminated and disposed. Therefore, an appropriate vacuum hole can be opened according to the fixing position of the work W, and the inside of the accommodation hole 1a can be decompressed to more firmly fix the work W.
